Noxious, invasive weeds can choke our streams and lakes and make it hard for fish, birds and wildlife to find food and shelter. Salmon have a difficult time going upstream to spawn when the stream is blocked by noxious weeds. Some weeds are poisonous and can cause rashes, illness or death in livestock or humans. Invasions of weeds have the potential to cause increased erosion and fire hazards, and reductions in recreational opportunities and land values. Managing weeds in aquatic environments such as lakes, streams and marine shorelines present unique challenges. The publications below are presented through WSU Extension. Please contact your county’s weed control board for a list of controlled species, specific weeds issues, and methods recommended for weed control in your area.
